Sorry to hear you are encountering all these problems. Could you tell me the

HDP,Ambari and OS type and version you are trying to install.

I will try to guide you.

@ilia kheifets

Are you running ambari server as "root" or non root user?

Do you have proper write permission (Read-Write) inside the following directory "/var/lib/ambari-agent/data"

?

i started the ambari agent with non root user

Hi @ilia kheifets,

Did you do the sudoer configuration for Ambari agents. If not please follow the doc and perform the steps, restart ambari agents and try to start the history server.

https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.0.3/bk_ambari-security/content/how_to_configure...

Thanks,

Aditya

HI, i tried it and indeed had to change the user under "run_as_user" but the error still exist

i also tried to do a new setup as root user (on a clean install and still have the same issue)

when i tried to run the command manually:

/usr/bin/python /var/lib/ambari-agent/cache/common-services/YARN/2.1.0.2.0/package/scripts/historyserver.py START /var/lib/ambari-agent/data/command-100.json /var/lib/ambari-agent/cache/common-services/YARN/2.1.0.2.0/package /var/lib/ambari-agent/data/structured-out-100.json INFO /var/lib/ambari-agent/tmp PROTOCOL_TLSv1

i receive the error

@ilia kheifets

What is your cluster size? what error especially are you experiencing?

Once you respond, I never experience such a problem n Ubuntu, will build a single node cluster and try to reproduce your error.


Explorer

for the test case i used a total of 3 computers

  1. ambari-server to manage all nodes
  2. amabri-agent to hold all managing services
  3. ambari-agent only worker services

the error mentioned in the first post, upon starting all services on all nodes, the History Server ,Hive Metastore ,HiveServer2 faill to start.

I made a simple step by step install, with no special configuration on fresh vm, based on clean images from http://www.osboxes.org

Mentor

@ilia kheifets

Curious though did you install ambari-agent on the ambari server too? If you didn't please do that and edit /etc/ambari-agent/conf/ambari-agent.ini to point to the new host.

[server]
hostname={Ambari-server_FQDN}
url_port=8440
secured_url_port=8441

Please le me know before I build an environment to reproduce your issue!

Explorer

I am doing a fresh install with root user
Ill give an update as soon as i finish

Mentor

@ilia kheifets

Its unfortunate we didn't drill down to resolve the issue but always remember to also install the ambari-agent on the Ambari server!

Keep me posted so I won't install and ubuntu 14 to resolve your problem.

@ilia kheifets

I don't see your updated thread though I have just received your update email. So you are still encountering the same problem.

What document did you use, if you have one can you share it.

Did you run the below on all the 3 nodes

# apt-get install ambari-agent

Can you confirm that this directory exists

/var/lib/ambari-agent/data/output-106.txt

Please revert

Explorer
 # apt-get install ambari-agent

only on server , i think user must install on each agent and register it only when using non root install (not auto vi ssh)

<em>/var/lib/ambari-agent/data/output-106.txt</em>

folder exists, but file does not

what did you mean by revert?

i tried multiple guides (for default settings all of them are exactly the same), but i just made a simple (next->next install with all default settings..)

for instance

Mentor

@ilia kheifets

revert justmeans get back to me I have just downloaded an Ubuntu 16.0.4 let me try it out.

The ambari-agent can be installed NOT only when using non-root but if you don't have passwordless configuration between the nodes.

# apt-get install ambari-agent

Give me some time

Mentor

@ilia kheifets

As promised I tried to recreate your environment on a 1 node cluster running Ubuntu 16.04 in a VM with 12 GB RAM.After the installations find below the high-level steps I performed.

The Cluster is installing without any issues

Generate public and private SSH keys on the Ambari Server host.

root@ubuntu17:~# ssh-keygen 

Accepted default values,copy the SSH Public Key (id_rsa.pub) to the root account on your target hosts if multi-node.

.ssh/id_rsa

.ssh/id_rsa.pub

Add the SSH Public Key to the authorized_keys file on your target hosts.

root@ubuntu17:~# cat id_rsa.pub >> authorized_keys 
root@ubuntu17:~# chmod 700 ~/.ssh 
root@ubuntu17:~# chmod 600 ~/.ssh/authorized_keys 

Set NTPD

root@ubuntu17:~# apt-get install ntp 
root@ubuntu17:~# update-rc.d ntp defaults 

Set the host FQDN in my case the Ambari server vi /etc/hosts ---- IP--FDN--ALIAS

 192.168.0.172 ubuntu17.kenya.com ubuntu17 

Edit host name

root@ubuntu17:~# vi /etc/hostname 
ubuntu17.kenya.com

Firewall settings

root@ubuntu17:~# sudo ufw disable 
The program 'setenforce' is currently not installed.So I installed

The program 'setenforce' is currently not installed.So I installed

root@ubuntu17:~# apt install selinux-utils 

Disable SE-Linux

root@ubuntu17:~# setenforce 0 

Set UMASK

root@ubuntu17:~# umask 0022 
root@ubuntu17:~# echo umask 0022 >> /etc/profile 

Download Ambari repo files

root@ubuntu17:~# wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu16/2.x/updates/2.5.2.0/ambari.list 

Grab the key

root@ubuntu17:~# apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD 

Update

root@ubuntu17:~# apt-get update 
root@ubuntu17:~# apt-cache showpkg ambari-server 
root@ubuntu17:~# apt-cache showpkg ambari-agent 
root@ubuntu17:~# apt-cache showpkg ambari-metrics-assembly 

Install Java Openjdk comes with JCE

root@ubuntu17:~# sudo apt-get install openjdk-8-jdk 

Install Ambari server here I used the root user

root@ubuntu17:~# apt-get install ambari-server 
root@ubuntu17:~# ambari-server setup 

Setup as root user with default postgres databases

root@ubuntu17:~# ambari-server start 
Ambari Server 'start' completed successfully. 

Get the FQDN for the ambari server

root@ubuntu17:~# hostname -f 
ubuntu17.kenya.com 

So my Ambari URL will be http://ubuntu17.kenya.com:8080

See attached screenshot,got an error with THP so had to disable

root@ubuntu17:~/.ssh# cat /sys/kernel/mm/transparent_hugepage/enabled [always] madvise never 
root@ubuntu17:~/.ssh# echo never > /sys/kernel/mm/transparent_hugepage/enabled 
root@ubuntu17:~/.ssh# echo never > /sys/kernel/mm/transparent_hugepage/defrag 
root@ubuntu17:~/.ssh# cat /sys/kernel/mm/transparent_hugepage/enabled always madvise [never]

Setup Mysql database for hive ,oozie etc

root@ubuntu17:~# sudo apt-get update 
root@ubuntu17:~# sudo apt-get install mysql-server 
root@ubuntu17:~# sudo mysql_secure_installation 
root@ubuntu17:~# apt-get install -y libpostgresql-jdbc-java 
root@ubuntu17:~# apt-get install libmysql-java 
root@ubuntu17:~# ls /usr/share/java/mysql-connector-java.jar 

Check that the mysql connector is present at that location

root@ubuntu17:~# ls /usr/share/java/mysql-connector-java.jar

Create the hive,oozie and ranger databases in Mysql with the correct privileges

created database for hive successfully

created database for oozie successfully

created database for ranger successfully

Run this command

# ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar

Proceeded with the cluster installation

http://ubuntu17.kenya.com:8080

i am waiting to see the outcome because most of the steps i made are exactly the same

exceptions:

  • Firewall setting - i did not disable cause the fw is not installed on the vm
  • java and sql- i set default so the ambari-server setup should get its default java and its own sql db
  • THP - had the error, but it only effects on performance, so i did not solve it on my use case, i wanted a working system at first
  • i used less services. i selected only spark2 and when pressing next enabled all its dependencies and required services
  • i used 2 nodes, one for all the service. and one only for clients\workes

Explorer

while one of my post is being moderated ill ask a another question:

why did you set a custom sql for hive ,oozie etc

Mentor

@ilia kheifets

Here we go all the services up and running without major issues !!!

Did you install java with JCE? standard procedure? I have seen your comments but at times we ignore the obvious well-documented steps. I followed usual steps and all is up and running.

As I have demonstrated that the procedure is OK and valid, this answered your question.
